We know, Given mass = Molar mass * Number of moles.
A.) <span>1.25 mol CaF</span>₂
Number of moles = 1.25
Molar mass = 78
So, Mass = 78 * 1.25 = 97.5 g
B.) 3.4 mol (NH₄)₂SO₄
Number of moles = 3.4
Molar mass = 132
Mass = 3.4 * 132 = 448.8 g
Hope this helps!
I believe it would be compound.
<span>The independent variable is the one that does not change depending on other variables - so here it would be the presence or the absence of caffeine - this is dependent on Tina's actions, but not on other variables in the experiment. The dependent variable is the heart rate - it is assumed to depend on the presence or absence of caffeine. A hypothesis could be that "Caffeine causes an increase of heart rate in earthworms" - and this hypothesis is what the experiment is testing.</span>
Answer:
c. they are all used to diagnose medical conditions
Explanation:
Lactate dehydrogenase, aspartate aminotransfcrase, and creatine kinase all are used to diagnose medical conditions.
Explanation:
(<u>Climate</u>, Weather) is an overall atmospheric condition of a place of 30 years and more while (Climate,<u>Weather</u>) is a condition for a short period of time.
2. (<u>Climate</u>, Weather) is influenced by latitude, altitude, ocean current, and topography.
3. The (<u>higher</u>, lower) the altitude, the (<u>colder</u>, warmer) the climate.
4. (<u>Windward</u>, Leeward) area of the mountain forms precipitation while (Windward,<u>Leeward)</u> gives dry air and warm weather.
5. Ocean currents bring (cold,<u> warm</u>) water and rain from the equator to the poles and (<u>cold</u>, warm) water from the poles toward the equator
